This inventicn relates to mourning e worl-zing member, and more particularly be such a rigid meunting of e Werking; mernioer suo jected to alternate unusual strains will take up ihese or stresses within 'llhis invention has utility when employed in excavators. @herein adopted, its action as e torsional iiioentieg elleetuelly prevents the severe? connections to the dipper from werlelng sash other an l. thereby loosening the flipper ironi its mounting on the directing member or handle.

Gonfsidering the fulcrum as at inionfi; bhe power as at bail 7, enrlilie weig tor Work 2141; teeth 6, this is a lever of the third class, The 1 unified mounting results in the" overlapping; power and weight; acting as one piece and being subjected only to shear and beird ing. The bolts 13holding the inembers lef e unified mounting together are nai su b jester]. to shear, but to tension as are bolts 5 holding the men'ibers of the unified mounting into position on the directing memher 4, and are non-shestr-si1staining, for the pocket formation of the mounting precludes "such result.

The structure disclosed is simple, of few parts, and moreover effective as a torsion absorbing mounting.

Theidee of the invent-ion herein disclosed is-not to belin ited. by the drawings and description to enj greater extent then. the ordinary meaning of the terms of the ele-irns demend; In other words, the elements forth in the Claims ere to he interpreted broadly, giving me the advantage of eqnivelents in the roteetion of my idea.
